Multi-particle crystal growth rates in vertical cones

Abstract

Experiments on the behavior and growth rates of potassium sulphate crystals suspended in the vertical cones by an upward flowing mother liquor were carried out. The crystals formed stable dispersed beds, of which the upper and lower limits and average positions were measured. The dissolution rates of crystals in the cones were measured and the liquid phase mass transfer coefficients were obtained. The growth rates of crystals were measured and considering the liquid phase diffusion resistance the rate constants of interfacial crystal formation were calculated and correlated.
